Call targetConfiguration() once before config is loaded and again afterwards in case the config needs to be changed to load from SD card etc
Drop SPI clock during binding
Remove debug
Add per device SPI DMA enable
Fix sdioPinConfigure() declaration warning
Reduce clock speed during SPI RX initialisation
* UART9 was supported as LPUART on some H7s.
* Newer 100-pin H7 CPUs support UART9 and USART10.
* 100+ pin devices support higher numbered UARTS than UART10.
Use USE_LPUART instead of hacking into UART9 for clarity.
* LPUARTS are different from other types of UARTS.
* They need different ID ranges.
* They have and different capabilities.
* Renumber LPUART1 to 40.
0-19 reserved for UART1-20
40-49 onwards for LPUART instances.
It makes sense to treat them as a different class of UART. Just like we
do for softserial, vcp, etc.
Implementation is DMA buffer based, just like the WS2811 LED Strip code,
so that there is minimal impact on flight performance.
Currently the code is mutually exclusive with the LED_STRIP code and
there is no means to set the transponder code.
Currently the interrupt handler is unused. Later it can be used as a
potential source for watchdog checking or to syncronize the system
around new acc/gyro data availability.
Verified on Naze32 rev 3/4/5 and SPRacingF3 targets.
- NVIC priorities are moved to separate file, all values are replaced wit symbolic names. Priorities should be the same.
- tiny change in DMA initialization
